《MATLAB信号处理超级学习手册》随书光盘， 《MATLAB信号处理超级学习手册》以MATLAB R2013a版本为基础，系统地讨论了数字信号处理的基本理论、基本分析方法、基本算法和设计方法，涉及了数字信号处理的各个方面，是一本比较全面的信号处理参考书。( MATLAB Signal Processing super study manual In MATLAB R2013a version of the basis, the system discussed in the basic theory of digital signal processing, the basic analysis methods, basic algorithms and design method involves all aspects of digital signal processing, it is a more comprehensive signal processing reference.)

matlab的随机数发生器，可以产生各种各样的随机序列，你懂的！(the producer of random sequence)

通过计算机上的多媒体卡，按照下列过程进行声音信号的录制、处理和回放，观察处理前后的波形，同时比较声音信号处理前后的效果。 1、 将录制的信号反褶以后播放（反褶以后的信号移到t=0点开始）。 2、 将录制的信号改变取样率（相当于进行了尺度变化）以后播放。 3、 将录制以后的信号延时1s，并将幅度降低一半，接着与原来的信号相加，然后播放。(Multimedia card on your computer, follow the process for recording, processing, and playback sound signal waveform observed before and after treatment, while comparative effectiveness sound signal before and after treatment. 1, the signal recorded after deconvolution player (deconvolution signal moves after t = start 0:00). 2, the signal is changing the sample rate recording (is equivalent to a scale change) later playback. 3, after the recorded signal delay 1s, and reduce the rate by half, and then with the original signal are added, then play it.)
